DESCRIPTION
groff is the GNU implementation of the roff document formatting system. It processes text files with embedded formatting commands to produce typeset output in various formats including PDF, PostScript, HTML, and terminal display.
The system includes preprocessors for tables (tbl), equations (eqn), and diagrams (pic), and supports multiple macro packages for different document types.
